摘　　要：采用酸溶法和碱融法两种消解方法处理同一铌钽矿石样品,利用电感耦合等离子体发射光谱法测定,计算了测定方法的检出限:Nb2O5为0.71μg/g、Ta2O5为1.41μg/g,对比了两种消解方法的准确度和精密度,两种方法的结果基本一致,能够满足要求。以及讨论总结了两种消解方法的优缺点。Two digestion methods of solution and alkali for dealing with a niobium tantalum ore sample melting by acid, determination of inductively coupled plasma atomic emission spectrometry, the detection limit of the method for the determination of calculation： Nb2O5 =0.71μg/g, Ta2O5 1.41 μg/g, the two kinds of digestion method accuracy and precision were compared, and the results were basically consistent, which can meet the requirements. The advantages and disadvantages of the two kinds of digestion method were discussed.
